[Thanh Tùng DZ]

so sánh A và B :

A = \(\frac{20}{39}+\frac{22}{27}+\frac{18}{43}\), B  = \(\frac{14}{39}+\frac{22}{29}+\frac{18}{41}\)

Answer 1

[Nguyễn Quang Tùng]

ta có 20/39 > 14/39

22/27 > 22/29

18/43 < 18/41

=> 20/39+22/27+18/43 > 14/39+22/29+18/41

ta có 20/39 > 14/39

22/27 > 22/29

18/43 < 18/41
